摘要:
The present disclosure provides a throwing device with a launcher and a propulsion system. The propulsion system comprises a retardant set between two sections of propellant for delaying the combustion and reducing the generated smoke or heat while launching the propulsion system. The launcher comprises: a tube for containing the propulsion system; and a trigger for triggering the ignition cartridge. A screw hole is in center of a bottom of the first chamber; nozzles are located around the screw hole; and a collar with a hole fixed in the bottom of the first chamber, wherein the ignition cartridge is fixed in the screw hole by the collar. The ignition cartridge comprises an explosive primer, and the launcher further comprises a firing pin triggered by the trigger to hit the explosive primer.

A socket structure is disclosed, comprising a base seat combined with an external cover, in which the top plane of the external cover has a socket panel, and a high-low tilted positioning plate is installed inside the external cover, with a high edge of the positioning plate being abutted by a movable abutting element, and the bottom end of the abutting element includes an elastic body; also, a release element is placed between the socket panel and the positioning plate, and the abutting element can be driven to move by means of a push button control located on one side of the socket panel.
摘要:
A request to resolve an IP address is received by a Domain Name Server (DNS). A record, such as an MX record, relating to the request is obtained that comprises a unique label (e.g. record=customer-com.mail.messaging.com) that is used in determining how to resolve the request. The unique label portion of the record (e.g. customer-com) is used to identify information relating to the request such as a version of software/service to use to handle the request, a region used to handle the request, and the like. The same record may be used to direct a request to a different version and/or different region. For example, without changing the record, a request at one time may access a first version/region and a request at a different time access a different version/region.

A solder bump structure for a ball grid array (BGA) includes at least one under bump metal (UBM) layer and a solder bump formed over the at least one UBM layer. The solder bump has a bump width and a bump height and the ratio of the bump height over the bump width is less than 1.
摘要:
Methods for forming lead zirconate titanate (PZT) nanoparticles are provided. The PZT nanoparticles are formed from a precursor solution, comprising a source of lead, a source of titanium, a source of zirconium, and a mineralizer, that undergoes a hydro thermal process. The size and morphology of the PZT nanoparticles are controlled, in part, by the heating schedule used during the hydro thermal process.
摘要:
A low power driving and sensing system for capacitive touch panels includes a capacitive touch panel, a first switch device, a second switch device, a driving device, a sensing device, and a control device. The capacitive touch panel has plural first conductor lines arranged in a first direction and plural second conductor lines arranged in a second direction. The driving device is connected to the first switch device for driving the capacitive touch panel. The sensing device is connected to the second switch device for sensing the capacitive touch panel. The control device configures the first switch device and the second switch device for entering the capacitive touch panel into a self-capacitance mode such that the driving device and the sensing device perform a self capacitance sensing, and into a mutual capacitance mode such that the driving device and the sensing device perform a mutual capacitance sensing.
摘要:
In a demodulation system for a low-power differential-sensing capacitive touch panel, the capacitive touch panel has n first conductor lines in a first direction and m second conductor lines in a second direction, and a mutual capacitance is generated at each intersection of the n first conductor lines and the m second conductor lines. The demodulation system has a signal generator, a detection circuit, a programmable gain amplifier, an analog to digital converter. During a driving cycle, the signal generator generates a pair of differential driving signals to drive two of the first conductor lines in the first direction for eliminating common noises of the two first conductor lines and avoiding the common noises from being amplified by the programmable gain amplifier.
摘要:
A work piece includes a copper bump having a top surface and sidewalls. A protection layer is formed on the sidewalls, and not on the top surface, of the copper bump. The protection layer includes a compound of copper and a polymer, and is a dielectric layer.
